Gray cast iron is basically a eutectic alloy composed of iron, carbon and silicon, in which carbon mainly exits in the form of graphite. To produce high-quality castings, it is very important to control the shape of the graphite formed duri...

Silicon Carbide has stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance. Its Mohs hardness is 9.5, second only to diamond. Pure silicon carbide is a colorless and transparent crys...

The production of silicon metal adopts the carbothermic method, that is, the method of smelting in a submerged arc furnace with silica and carbonaceous reducing agent. The purity of the silicon prepared in this way is 97% to 98%, and such si...

There are several minor metal elements, like Nickel, Molybdenum, Vanadium, Tungsten, Niobium and Cobalt. Unlike other usual metal or non metal elements, they only occupy little part of the total chemical composition of the final steel or iro...

The ferroalloy production is a process in which furnace charge, reducing agent, slag material, and composition regulator undergo physical and chemical changes at high temperatures to generate alloy, slag, and furnace gas. ...

The problem of residual elements in steel is one of the important problems faced by the metallurgical industry. In the steel-making process, steel-making raw materials will bring a large amount of impurity elements into the furnace....

In the process of smelting synthetic cast iron, due to the large amount of scrap added and the low content of C in the molten iron, the recarburizer must be used to increase carbon....

Chrome, Aluminum, Copper and Titanium are 4 types of metal elements, they all can be elemental metals in industry manufacture, made into all kinds of metal product depends on their own variable performances. In steel/iron, with different per...

Sulfur is derived from steel-making ore and fuel coke, and is a harmful element in steel. Sulfur exists in the steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985C) compound, and the hot working temperature of s...

The application of RE in conductive aluminum alloys is currently a field in my country that has a wider range of applications, more mature technology, higher industrial value and better economic benefits.........

The role of carbon in steel is a double-edged sword. As the carbon content increases, the yield point and tensile strength of the material will gradually increase, but the plasticity and impact properties will decrease. Therefore, the carbon...

After inoculation, the cast iron with spherical graphite replaces the usual flake graphite cast iron, which is called ductile iron. Now briefly summarize the precautions for producing ductile iron....
